It's a Dangerous Time... to be a team mascot in the DC area. First, Sheila Johnson turned Charm into wabbit stew. Seems she has a love affair with pandas. (Never mind that the ones in the National Zoo belong to China.) Now the Washington Post is reporting that Gunston, the green fuzzy mascot of George Mason University, is facing demotion, despite having gained national recognition this year when GMU became the Cinderella team of the men's NCAA tourney. What's next? Melting down Slapshot into hockey pucks?
